-Subject: [PATCH 280/454] gpiolib: Don't prevent IRQ usage of output GPIOs
-
-Upstream Linux deems using output GPIOs to generate IRQs as a bogus
-use case, even though the BCM2835 GPIO controller is capable of doing
-so. A number of users would like to make use of this facility, so
-disable the checks.
